An oil bath is a type of heated bath used in a laboratory, most commonly used to heat up chemical reactions. It is a container of oil that is heated by a hot plate or (in rare cases) a Bunsen burner .
Most water baths have a digital or an analogue interface to allow users to set a desired temperature, but some water baths have their temperature controlled by a current passing through a reader. Uses include warming of reagents , melting of substrates , determination of boiling point , or incubation of cell cultures.
A thermic fluid heater (TFH), [1] also known as a thermal oil heater, is a device used for indirect heat transfer through a thermic fluid. It heats the fluid to a desired temperature and then transfers that heat to various processes without any direct contact between the heating source and the product.
Solid state fermentation uses culture substrates with low water levels (reduced water activity), which is particularly appropriate for mould. The methods used to grow filamentous fungi using solid state fermentation allow the best reproduction of their natural environment. The medium is saturated with water but little of it is free-flowing.
The driving force for dewetting is the minimization of the total energy of the free surfaces of the film and substrate as well as of the film-substrate interface. [7] The dedicated heating stage in SEM has been widely used to accurately control sample temperature through a thermocouple to observe the in-situ behaviour of the material, and can ...
Chemical Bath Deposition has a long history but until recently was an uncommon method of thin-film deposition. [1]In 1865, Justus Liebig published an article describing the use of Chemical Bath Deposition to silver mirrors (to affix a reflective layer of silver to the back of glass to form a mirror), [5] though in the modern day electroplating and vacuum deposition are more common.
A bioactive compound is a compound that has an effect on a living organism, tissue or cell, usually demonstrated by basic research in vitro or in vivo in the laboratory. While dietary nutrients are essential to life, bioactive compounds have not been proved to be essential – as the body can function without them – or because their actions are obscured by nutrients fulfilling the function.
The substrate is activated in a small part of the enzyme's macromolecule called the active site. There, the binding of a substrate close to functional groups in the enzyme causes catalysis by so-called proximity effects. It is possible to create similar catalysts from small molecules by combining substrate-binding
